WALTER ALLAN BOCKIUS, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE BECKLEY-RALSTON 00., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

TOOL FOR DRIVING BEARING-SLEEVES FROM SOCKETS.

Specification of Letters Patent. Patented Dec. 16, 1919.

Application filed June 21, 1916. Serial No. 104,875.

To all whom it may concern.-

Be it known that I, IVALTER ALLAN Bocmns, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tools for Driving Bearing-Sleeves from Sockets, of which the following is a full, clear, and exact description.

The invention relates to tools for driving bearing sleeves from sockets and more particularly one which is adapted for use on the steering knuckles on automobiles.

The object of the invention is to provide a device for this purpose which is exceedingly simple in construction, efficient in operation, which can be conveniently carried in a tool kit and which can be produced at a low cost.

The invention consists in the improved tool hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Figure 1 is a view showing the tool in a steering knuckle which is shown in section. Fig. 2 is a perspective showing the tool withdrawn from the socket.

The improved tool is formed of a round bar or rod3 of metal. One end of this rod is knurled, as at 4, to provide a gripping surface for pulling the tool longitudinally through a socket. A portion of the other end of the bar is formed with a slit 5 which is cut transversely through the bar for a suflicient distance to provide integral resilient members 6 which are sprung outwardly so they will automatically spread when they are forced through a sleeve.

The steering knuckle 7 is usually provided with bearing sleeves 8 driven tightly into the ends of the socket so they will not rotate therein. In practice, it occasionally becomes necessary to replace or renew these sleeves, and the purpose of the tool is to provide means whereby either of these sleeves may be driven from the socket. The sleeves are usually flanged at their outer ends, as at 9, so they must be driven from the opposite end of the socket in which they are held. In operation, when the lower socket is to be removed, the upper end of the bar 3 is passed through the opening in the lower sleeve 8 from the bottom thereof. The upper portion of the tool will pass freely through the sleeve 8 and the mem bers 6 will be contracted by the lower sleeve as they are pulled therethrough. After the lower ends of members 6 have cleared the upper end of the lower sleeve 8, they will automatically spring outwardly to engage the sleeve ends and then the tool may be driven by the hammer against the upper end of the bar 3 to force the sleeve out of the socket. To remove the upper sleeve 8, the bar 3 is passed through the socket from above.

The invention exemplifies a one-piece tool which is simple in construction and serves as convenient means for driving the sleeves from the sockets of steering knuckles.

The invention is not to be understood as restricted to ,the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:

1. A tool for driving sleeves from sockets, formed of a rod and comprising a stem adapted for the application of a driver and being slitted longitudinally adjacent its other end, the portions adjacent the slit being resilient and contractible and normally spread and having ends for engaging the end of a sleeve, the entire stem being less in width than the extreme width of the sleeve-engaging ends to adapt the stem to be passed through a sleeve which the tool is adapted to engage.

2. A one-piece tool for driving sleeves from sockets, formed of a rod and comprising a stem adapted for the application of a driver, and being slitted longitudinally adjacent its other end, the portions adjacent the slit being resilient and contractible and normally spread and having ends for engaging the end of a sleeve, the entire stem being less in width than the extreme width of the sleeve-engaging ends to adapt the stem to be passed through a sleeve which the tool is adapted to engage.
